Neutron-loaded outflows in gamma-ray bursts
Elena M. Rossi, Andrei M. Beloborodov, Martin J. Rees
Relativistic neutron-loaded outflows in gamma-ray bursts are studied at their early stages, before deceleration by a surrounding medium. The outflow has four components: radiation,…
Possible evidence for the ejection of a supermassive black hole from an ongoing merger of galaxies
Martin G. Haehnelt, Melvyn B. Davies, Martin J. Rees
Attempts of Magain et al (2005) to detect the host galaxy of the bright QSO HE0450--2958 have not been successful. We suggest that the supermassive black hole powering the QSO was…
Dimensionless constants, cosmology and other dark matters
Max Tegmark, Anthony Aguirre, Martin J Rees +1
We identify 31 dimensionless physical constants required by particle physics and cosmology, and emphasize that both microphysical constraints and selection effects might help eluci…
The observable effects of a photospheric component on GRB's and XRF's prompt emission spectrum
Asaf Pe'er, Peter Mészáros, Martin J. Rees
A thermal radiative component is likely to accompany the first stages of the prompt emission of Gamma-ray bursts (GRB's) and X-ray flashes (XRF's). We analyze the effect of such a…
Rapid growth of high redshift black holes
Marta Volonteri, Martin J. Rees
We discuss a model for the early assembly of supermassive black holes (SMBHs) at the center of galaxies that trace their hierarchical build-up far up in the dark halo `merger tree'…
Core-Collapse Very Massive Stars: Evolution, Explosion, and Nucleosynthesis of Population III 500 -- 1000 Stars
T. Ohkubo, H. Umeda, K. Maeda +4
We calculate evolution, collapse, explosion, and nucleosynthesis of Population III very-massive stars with 500 and 1000. Presupernova evolution is calculated…
